Zhangqiu concrete die Floor
Concrete molding floor is widely used. It can be applied to all kinds of ground and commercial pavements such as municipal, urban construction, commerce, residential quarters and landscapes, even including swimming pools, squares, sidewalks, driveways, amusement parks, subway platforms, parking lots, etc. Even many * * * hotels, entrances and exits of building buildings, theme restaurants, roof gardens, etc. also like to choose Jing stone color embossing floor.
Concrete construction requirements for base course of concrete molding floor one The strength of base concrete shall be ≥C25 The water cement ratio shall be as small as possible and the tamping shall not contain early strength agent. two Particle size of crushed stone aggregate in concrete ≤30mm And the foundation surface must be paved with crushed stone aggregate ≤15mm thickness ≥10mm Of cement mortar Layer. three The slump of concrete shall be controlled within 3-4cm The slump of commercial concrete shall be controlled within 12-14 cm 。 four Crushed stone and plain soil foundation must be compacted or tamped with a roller. five 、 10 cm For the following concrete vibration Flat Vibrating operation with type vibrator, 10 cm The above concrete shall be vibrated by immersion. six Use heavy steel long rollers (the steel rollers should be wider than the formwork zero point three (m above) repeatedly roll the platform to make the platform level. When rolling the platform, remove the foreign matters on the steel roll. Lift out the concrete slurry to ensure that there is no sand In case that steel rollers cannot be used for operation, template scrapers shall be used to make the platform level. seven After the concrete platform is leveled, bleeding treatment shall be carried out. eight The grading of bottom concrete is required to be C25 or C20 , the upper layer is C30 or C25 Mortar fine aggregate concrete with a total thickness of 5-20 cm 。
Four elements of concrete molding floor:
1, Traffic safety
Concrete molding floor can prevent the vehicle from skidding in adverse weather , Reduce the distance from the previous vehicle by approx 40%, Avoid accidents caused by overhead rear end collision or turning. At present, in some municipal projects , Various eye-catching traffic signs in different colors have been added to meet the needs of customers , The concept of imprinted concrete is not limited to the pure floor function.
2, Color matching
Provide high-performance concrete molding floor with different colors Color block for customer selection , Of course, it can also be deployed according to customer needs. Because of the rich colors and patterns , The supply of goods is sufficient.
3, Material selection
Due to the addition of concrete molding floor in fine aggregate Protective agent , In this way, the imprinted concrete will not fade or fall off , Shiny as new , It saves the cost of future maintenance. At the same time, sound absorption function is also a major feature , Can be lowered in downtown area three to four Decibel noise.
4, Construction operation
While maintaining quality and quantity , Fast completion , Secondly, the working area is small , The laying effect is immediate , The above two points also greatly reduce the road occupation time due to construction.
